Summary:
In 3rd generation mobile cellular systems such as W-CDMA and 4th generation mobile cellular systems, spatial processing techniques such as Multi-Input-Multi-Output (MIMO) techniques are being investigated. In order to accurately assess the performance of these spatial processing techniques for wideband mobile communication systems, a Time-Spatial Propagation (TSP) model that can simulate the characteristics of both the delay profile and the spatial arrival angular profile for travelling waves at the same time is required. We proposed a TSP model in Non-line of sight (NLOS) environments for wideband mobile communication systems using UHF and SHF bands. Proposed model can predict the delay profile and the arrival angular profile in NLOS environments at the same time [1]-[4]. On the other hand, TSP model in line of sight (LOS) environments is necessary in order to evaluate these processing techniques in LOS environments. This paper proposes a TSP model in LOS environments developed based on filed measurement data. This model can consider the propagation conditions such as BS antenna height, distance between BS and MS, and structure of surrounding buildings as well as the TSP model in NLOS environments.
